(a)
Number of books that students in Class 1C read = 60
Number of books that students in Class 1D read = 120
Number of books that students in Class 1C and 1D read
= 60 + 120
= 180
(b)
Number of books that students in Class 1B read more than students read in Class 1D
= 210 - 120
= 90
Number of gifts that students in Class 1B exchanged more than students in Class 1D
= 90 ÷ 2
= 45
